Thank you for this clarification.

Yeah, I understand that ingress LU performs lookup. I meant the case of
MX80. It's actually the case of local switching in MPC1 but with twice as
many interfaces. Where it's backplane->ethernet direction in MPC and LU does
not do lookups, in MX80 it's built-in-XE->MIC direction and LU must perform
lookups. Having said MQ is capable to transfer close to 70 Gigs, in case of
small packets the LU limitation comes into play much earlier (when MQ only
transfers close to 30 Gigs), doesn't it?
